On Semiconductor AR0521
The new ON Semiconductor AR0521, available from Framos, is a 1/2.5” image sensor with a 5 Megapixel resolution, offering 60 fps for excellent video performance. The 2.2 µm Back Side Illuminated pixel technology enables clear, sharp digital pictures while the sensor’s ability to capture both continuous video and single frames makes it the perfect choice for security applications. A demo kit is available for the AR0521 along with additional services provided by the global imaging experts at FRAMOS.
The AR0521 captures images in either linear or high dynamic range modes with rolling shutter readouts and includes additional functions such as binning and subwindowing in both video and single frame modes. It is designed for both low light and high dynamic range performance, with line interleaved T1/T2 readout that support off chip HDR algorithms in an ISP chip.
Sibel Yorulmaz-Cokugur, sensor expert at FRAMOS, explains the advantages of ON Semiconductors AR0521: “The new AR0521 is a fast surveillance sensor with high sensitivity and an excellent image quality for precise recognition and analysis. In comparison to its predecessor, the MT9P006 sensor, it provides an 18% increase in Quantum Efficiency (QE) at 550nm along with 33% in the NIR region, which is important for most of our surveillance customers. The AR0521 makes surveillance more secure by providing better images under challenging conditions while its small form factor eases the integration in OEM and embedded vision projects.”
In addition, the excellent image quality is supplemented by several digital processing functions, including digital gain, dynamic defect correction and a digital shading correction block that compensates for color/brightness shading that is introduced by the lens and the sensor’s chief ray angle (CRA) curve mismatch. The full resolution image can be outputted at 60 frames per second (fps) in linear mode and 30 fps in line interleaved high dynamic range (HDR) mode output through either the MIPI or HiSPi ports. The maximum data rate for MIPI is 1.2 Gb/second and 1.0 Gb/second for HiSPi. The AR0521 is designed to operate over a wide ambient temperature range of -30°C to +85°C which aligns with a wide range of applications in rough environments. It also supports advanced line synchronization controls for multi-camera (stereo) support. Evaluation samples of color sensors are now available.
Industry and product experts at FRAMOS are available to support customers with the integration of these new sensors in their applications and projects. In addition, FRAMOS provides services like development support, customization, and logistics that speed development and improve time to market for all vision products.
